Revelation 9:17-19

Revised Standard Version Catholic Edition

¹⁷ And this was how I saw the horses in my vision: the riders wore breastplates the color of fire and of sapphire^[a] and of sulphur, and the heads of the horses were like lions’ heads, and fire and smoke and sulphur issued from their mouths. ¹⁸ By these three plagues a third of mankind was killed, by the fire and smoke and sulphur issuing from their mouths. ¹⁹ For the power of the horses is in their mouths and in their tails; their tails are like serpents, with heads, and by means of them they wound.
